Application inea January 1s, i912. sei-iai No. 671,015.

To all whom it may concern:

Be it known that I, 1WILLIAM C. Giri'- sci-Iow, a citizen of theUnitedStates, residing at Littleton, in the county -of Arapa hoe YandState of Colorado, have invented new l'and useful Improvements inCombined Levels and Plum'bs, of which the following is a specification.

This invention relates to a plumb and level device intended for use bycarpenters, mechanics and the like whereby horizontal, perpendicular andintei'niediate lines can be quickly and accurately obtained.

The invention has for one of its objects to improve and simplify theconstruction of devices of this character so fas to be comparativelysimple and inexpensive to manufacture, and convenient and reliable inuse.

Another object of the invention is the provision of a Weighted indexdevice having a plurality of hands, one of which is used for obtainingthe level and viewed through an opening in the top of the stock of thedevice, and the other or others for obtaining plumb or other inclinedlines, and arranged to be viewed through the sides of the stock, theside index hands being movable over graduated rings to indicate thedegrees.

Vith these objects in view and others, as will appear as the descriptionproceeds, the invention comprises the various novel features ofconstruction and arrangement of parts which will be more fully describedhereinafter and set forth with particularity in the claims appendedhereto.

In the accompanying drawing, which illustrates one of the embodiments ofthe invention, Figure 1 is a side view of the instrument withintermediate portions broken away. Fig. 2 is a similar view with aportion of one of the side strips removed. Fig. 3 is a longitudinalsectional view. Fig. 4L is a vertical transverse sectional view drawn onan enlarged scale and taken centrally through the device. Fig. 5 is aperspective view of the compound index. Fig. 6 is a perspective view ofthe top cover glass.

Similar reference characters are employed to designate correspondingparts throughout the views.

Referring to the drawing, A designates the stock or bar of theinstrument which, at its center, is provided with a central chamber 2 inwhich is arranged the index B This index comprises a metal body 3provided with fa main index hand 4 and side secondary index hands `5,there being a pivot shaft 6 extending from one side to the other jandformed at its ends into sharp p'oints or journals 7, the body 3 beingcupped out at 8 for receiving the bearings 9 for the journals. Thesebearings are screws carried by bracket-s 10 suitably secured to thestock A, the screws having their 'ends hollowed out to receive thepoints of the pivot shaft 6. The bottom of the body 3 of the compoundindex is formed with 'a depending lug` or tongue 11 to which is attacheda weight 12, tire weight being chambered out at its top for receivingthe lug, which latter is connected with the weight by a pintle 13passing through the lug` and the sides of the weight. By means of thisweight, the index 'device B will always assume a vertical position sothat the hands thereof will indicate the position of the stock withrespect to the plumb line.

The chamber 2 of the stock has top and bottom openings 14e and 15disposed vertically in line with the main hand Ll and these Openings arecovered by glass plates 16 that are each provided with a central indexline 17, the glass plates heilig set into the stock A. and secured inplace by retaining` plates 18 that have openings 19 through which theindex lines 17 can be observed. By having top and bottom openings, theinstrument can be reversed so that either side can act as the top. Thechamber 2 is opened at its top to permit the secondary index hands to bediscerned and these hands move over graduated rings or dials 20 dividedinto degree marks so that any angle perpendicular or otherwise to thehorizontal can be noted and one or the other hand 5 will be alwayswithin view.

In the present instance, the stock A is composed of a central section 21and side sections 22 secured to the central section by screws 23. Theside sections have circular openings 211 for exposing the weighted indexdevice and these openings are covered by glass plates 25 having theirvertical edges set into grooves in the stock, or in any other well knownmanner. Set into the sides of the central section are rectangular plates2G that have circular openings 27 to accommodate the device B and therings 20 are secured to these side plates 26, the plates being securedto the main section 2l by screws 2S.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of operation Will be readily apparent to those skilled in the artto Which the invention appertains, and While I have described theprinciple of operation of the invention, together with the device WhichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made When desired as are Within the scope of the claimsappended hereto.

Having thus described the invention, what 1 claim is 1. An instrument ofthe class described comprising a stock having a chamber opening throughits side and top Jfaces, transparent coverings for the chamber openings,a Weighted index arranged Within the casing and provided with a centralhand and a side hand, a pivot shaft for said index, bearings in whichthe ends of the shaft are journaled, and a graduated ring secured to thestock concentric With the index pivot for cooperation with the sidehand, the covering for the top openings being provided with an indexline for use in conjunction With the central hand.

2. An instrument of the class described comprising a stock having achamber opening through its side face and its top and bottom faces, atransparent covering for the side opening, transparent coverings for thetop and bottom openings provided With index lines, a Weighted indexarranged Within the casing and provided With a central hand for use inconnection With the index lines of the top and bottom openings and witha side hand, a pivot shaft upon Which the index is mounted, bearingsprovided upon the stock in which the ends of the said shaft arerotatably mounted, and a graduated ring provided upon the stockconcentric with the index pivot for cooperation with the side hand.

In testimony whereof I aiiix my signature in presence of two Witnesses.
